Major League Baseball is the stuff of Americana and nostalgia, but it’s also trying hard to keep up with the 21st century. Today, MLBAM, its interactive/digital media subsidiary, said that it has inked a deal with Qualcomm, for the latter to provide technology and engineering support to improve mobile networks at 30 Major League Baseball ballparks. The deal follows an agreement struck between T-Mobile and MLBAM in January for the mobile carrier to help finally break the wired link between dugout and bullpen, and comes as the two parties forecast one-thousand-fold demand for mobile data in ballparks in the near future.
